The Blackle Debacle

Directory of technologies and resources relating to Computer Screen Energy Use.

Do we save or use more power when we use black as a background on a computer screen? If you still have a CRT display, then Blackle makes sense. If you use a flat-screen display, which has been the majority for a few years, the opposite effect takes place. Black on an LCD display uses more energy than when using a white background.

Does a Darkened Google Really Save Electricity? - The savings are most likely to accrue from older CRT (cathode-ray tube) monitors, rather than the more-modern, more-compact, more-energy-efficient LCD (liquid crystal display) screens that have come to dominate the market (representing three quarters of all monitors world-wide as of last year, by some estimates).

The law of unintended consequences kicks in. If you still have a CRT display, then Blackle makes sense. If you use a flat-screen display, the opposite effect takes place. Black on an LCD display uses more energy than when using a white background. Blackle is not a program. It is a website designed to get you to use in order to generate Google revenues for Heap Media in Australia.
